The CONST_DMUS_CURVES enumeration is used to define the shape of a curve in the DMUS_CURVE_PMSG type.
Syntax
Enum CONST_DMUS_CURVES
  DMUS_CURVES_EXP     = 2 
  DMUS_CURVES_INSTANT = 1 
  DMUS_CURVES_LINEAR  = 0 
  DMUS_CURVES_LOG     = 3 
  DMUS_CURVES_SINE    = 4 
End Enum
Constants
DMUS_CURVES_EXP
Exponential curve shape.
DMUS_CURVES_INSTANT
Instant curve shape (beginning and end of curve happen at essentially the same time).
DMUS_CURVES_LINEAR
Linear curve shape.
DMUS_CURVES_LOG
Logarithmic curve shape.
DMUS_CURVES_SINE
Sine curve shape.
